Real-time Computer Vision With Ruby - OSCON 2008

Computer vision software requires image- and video-file-I/O as well as camera access and fast video display. Ruby and existing open source software allowed us to develop a machine vision library combining performance and flexibility in an unprecedented way. Native array operations are used to implement a variety of machine vision algorithms. This research was funded by the Nanorobotics grant.

Introduction
Innovation Happens Elsewhere
Ron Goldman & Richard P. Gabriel
“The market need is greatest for platform
products because of the importance of a
reliable promise that vendor lock-in will not
endanger the survival of products built or
modiﬁed on the software stack above that
platform.”
“It is important to remove as many barriers to
collaboration as possible: social, political,
and technical.”

Respect The Freedom Of Downstream Users (Richard Stallman)
GPL requires derived works to be available under the same license.
Covenant Not To Assert Patent Claims (Eben Moglen)
GPLv3 deters users of the program from instituting patent ligitation by
the threat of withdrawing further rights to use the program.

GPLv3 has regulations against DMCA restrictions and tivoization.
